Present Water Supply Scenario:

At present, most of the Habitations are getting water from local and near by Bore Well Sources. Some of the habitations have been provided with water supply from Infiltration Wells in River Vaipar, River Arjuna, Gundar and River Vaigai. Moreover, the Rivers mentioned above are not perennial. The present level of service to the rural areas is 10 lpcd.

Need For The Proposal:

In Virudhunagar District, all the existing Bore wells and Open Wells are not sustainable. The Rivers flowing within this District are also not perennial. In order to enhance the level of service as per the norms, it is necessitated to formulate the above CWSS with River Tamiraparani as source.

Population and Requirement:

The population has been forecasted for the base year (2012), intermediate (2027) and ultimate stages as 3.53 Lakhs, 3.88 Lakhs and 4.24 Lakhs respectively.

Water requirement has been worked out as 13.08 MLD and 14.26 MLD for the intermediate (2027) and ultimate (2042) stages, respectively by adopting pro-rata of 40 lpcd including the existing sustainable supply of 10 lpcd for Rural habitation.

Description of Proposal:

It is proposed to tap sub surface water of 14.26 MLD in River Tamiraparani near Vallanadu by providing 12 Nos of Infiltration Wells. Water from 6 Nos of wells (Murappanadu site I) will be pumped to the 1LL Stand post and then gravitated to the common sump of capacity 6.25 LL at Murappanadu. Water from another 6 wells (Murappanadu site II) will also be pumped to the common sump. Water from this common sump will be pumped to 2 Intermediate Boosters and then to 139 nos. of rural sumps to feed the beneficiaries. The total length of transmission main is 1282.18 km (612mm to 200mm- DI pipe and 160mm to 50mm- Pvc pipe). In addition to the 702 nos of existing Service reservoirs, 49 nos are newly proposed. The water collected in the Service Reservoirs will be distributed to the Public through 624.35 km of existing Distribution system and 11.50 km of proposed Distribution system.

Cost:

Administrative Sanction accorded in GO.MS.NO.167/MA&WS (WS2) Department dt.11.8.10 for Rs.190 Crore. Subsequently, the Detailed Project Report was reviewed by the Third Party Independent Consultant engaged by TNUIFSL and revised to Rs.191 Crore to install and Rs.5.15 Crore to maintain annually.
